HI,
I am not really a fan of the angled roll bars, but yours does at least look the best of the ones I have seen, I think because you haven't introduced a new angle by matching the bar with the windscreen and the seats.
But as you say it is V1.0 so if I was to design V.20 for you I would bend the bar vertical just above the top seat belt mount, much like the top of the seats stand vertical. And I would bring the two rear bars to meet the side bars just below the seat belt mount or lower, whatever matches the angle on the guards.
And the angle on the hood bows looks wrong, it should be more or less flat across the top between the two hoops, with maybe a slight bias towards the front.
